Alex had a secret transformation, like Gamer did (since it's not a secret anymore). Unlike Gamer, he transformed every time the sun went down. But it wasn't into a werehog.
When Alex transforms, his canines grow to an inch long, his jeans and shirt vanish, his gloves and fur turn solid black, his quills get rough edges, his shoes turn solid dark blue, his irises turn black, his pupils turn red, his skin turns dark blue, sharp claws extend from his gloves, and he ends up with sharp spikes coming from his tail. He was a vampire at night. (Unusual, right?)
Just like Gamer when he goes Dark, whenever Alex transforms into Vampire Alex, his powers get 10 times stronger. So he could also fly 10 times faster, teleport in 10 times more situations, his telekinesis becomes 10 times more powerful, and his energy bombs are 10 times more powerful.
He didn't want anyone to find out about it since he thought he was a monster like this, so he teleported so that he was deep in the middle of the forest at night so that when the sun went down, no one would see him. Since vampires need blood, he also went into the middle of the forest so that he would be surrounded by predators. When he transforms into Vampire Alex, he's able to kill any predators that come after him and drink their blood. He hated it, but he couldn't do anything about it.
It's been like this for him for 6 years. But soon, his carefully hidden secret will start to become known.
